My friend is suicidal

My friend just texted me and said, hinting towards is very obviously that he's gonna take his own life in three days. Next week is finals. I've known that he's been depressed for a few months but he has a therapist and is taking medication and didn't realize its as bad as it is. Please help. I don't know what to do and I am extremely worried. I apologize if I put this threat in the wrong topic.

I think your best plan would be to contact someone and let them know, his parents would probably be best. If he's given a time line on when, you can't not take it seriously. He does need help, he's reached out to you.
I hope this helps.
